Definitions
- the present invention relates to an electrical Controllable hysteresis brake according to the preamble of Claim 1.
- Hysteresis brakes provide a braking torque, which regardless of the speed. In contrast to eddy current brakes owns hysteresis brakes also in the Standstill a braking torque.
- the mode of operation of hysteresis brakes is based on magnetic force acting on attractive poles in synchronous operation and on permanent remagnetization of a permanent magnetic Material in the slip mode.
- Hysteresis brakes are used in traction and braking torque control systems used; they can be considered magnetic Exciter part of an electromagnetic coil or have a permanent magnet.
- Electrically controllable hysteresis brakes are u.a. for the sensitive control of winding processes or also for drives with precisely adjustable, non-contact Torque transmission used.
- the power supply of the electromagnetic variants usually takes place directly via a connection line or in the cases that the components themselves rotate over slip rings (e.g., basket twisting machines).
- washing heads are by repelling the cleaning water, that shoots out of the nozzles, in rotation added. Since the rotational speed is unbraked until the Inefficiency of the water jet would rise the rotation must be braked. Again, there is an electrical Supply line usually not possible.
- a permanently magnetically excited brake is here problematic because the wash water in a temperature range from about 5 ° C to 95 ° C can be used and the temperature changes during use. As a result, the torque generated over the temperature variation of the magnetic material of the exciter magnet a change, in turn, the number of revolutions of the washing head rise and fall very much leaves. This effect makes the system uncontrollable, and influences the washing result accordingly.
- US-A-5 986 370 shows a brake unit with a Electromagnetically controllable brake with a internal power source for power and with Means provided for regulating the power supply is.
- the present invention is based on the object independent from an electrical connection, electromagnetic and thus largely independent of temperature Specify brake system whose moment also set during a running process and can be varied.
- the brake unit is a hysteresis brake and comprises a receiving unit, those with the means to regulate the power supply is connected, wherein by means of the receiving unit via a transmission / control unit the setting and Adjusting the torque wirelessly takes place in such a way that they operate independently of a connection line can be.
- the power source is a battery or a rechargeable battery. This creates a self-sufficient unit, operated independently of a connection line can be.
- the adjustment and adjustment of the torque can by wireless remote control from a remote Transmission unit.
- control loop is in a computing unit integrated of the receiver. This has the Advantage that transmission errors are minimized.
- control loop is integrated in the transmitting unit.
- a parallel electrical generator via a Charge controller charge the battery during operation.
- the invention has the advantage that the hysteresis brake can also be operated if a supply line due to the circumstances is not feasible.
- the independence of the torque from the temperature ensures: Unlike a permanent magnet system the generated torque depends only on the coil current, so that this form the manipulated variable of a control loop can. The torque can accurately, without stopping the process, set or variable process parameters be adjusted.
- the hysteresis brake according to the invention is shown formed as a self-sufficient unit 1.
- This includes the hysteresis brake 2, which by means of a battery or a battery 3 is supplied with power.
- a control unit 4 provided to adjustment and adjustment of the torque.
- the coil current forms the manipulated variable of a control loop, wherein the corresponding arithmetic unit integrated into the control unit is.
- the adjustment and adjustment of the torque takes place by remote control from a remote transmitter / controller 5, with a receiving unit. 6 communicated.
- the operation of the hysteresis brake is also then granted if there is a supply due to circumstances is not realizable, with the torque during the Operation can be set exactly.
- Figure 2 shows an application of a variant of erfindungesammlungen Hysteresis brake as part of a rotating Washing head 7, by means of recoil of the cleaning water, that shoots out of the nozzles, in rotation is offset.
- the receiving unit 6, the control unit 4 and the transmission / control unit 5, the hysteresis brake 1 has a charge controller 9.
- the battery by means of a parallel switched electric generator 8 via a Charge controller 9 charged during operation.
- the washing head can be particularly space and cost operate.
- Figure 3 shows a further application of erfindungesammlungen Hysteresis brake in the context of a twisting machine.
- an outer thread 9 rotates by 360 ° around an inner thread 10, such that a supply line for the power supply of an electromagnetic hysteresis brake becomes impossible.
- an electromagnetic hysteresis brake be used as shown in Figure 3, since according to the Invention, the power supply without supply takes place.
